Graffiti abatement is a process of getting rid of graffiti. Graffiti is when someone paints on a wall, building, or other surface without permission. People often do it to express an opinion or tell a story. Some people think graffiti is an eye-sore, so they get rid of it by cleaning it up or painting over it. This is called graffiti abatement. It is important to fight against graffiti because it can make neighborhoods look bad and discourage businesses from investing in them.
